T9115 CVD Grade: High-Speed Steel Specialist
The T9115 grade is a flagship Tungaloy coating designed for stable and efficient steel turning. The long-tail keywords industry favorite utilizes a multi-layered CVD coating that offers a perfect balance of toughness and hardness. This prevents plastic deformation even at high cutting speeds, ensuring your CNC machining productivity remains at its peak.
The 24 Chipbreaker
The 24-style chipbreaker is a double-sided geometry optimized for finishing to light-medium cutting. It provides a wide chip-breaking range, which is critical for maintaining surface integrity and preventing workpiece damage in precision machining.
Recommended Cutting Parameters
Optimized for P (Steel) Applications:
-
Cutting Speed (Vc): 150 - 350 m/min (490 - 1150 SFM)
-
Feed Rate (f): 0.05 - 0.20 mm/rev
-
Depth of Cut (ap): 0.2 - 1.5 mm
*Pro Tip: For high-speed finishing, utilize the upper range of Vc to reduce tool pressure and improve surface finish.*
Global Verified Reviews
⭐⭐⭐⭐⭐ "Workhorse for Steel" - Hans G., Germany
"T9115 is my go-to for production runs on alloy steel. The tool life is very predictable, and the 24 chipbreaker is great for finishing."
⭐⭐⭐⭐⭐ "Sharp and Reliable" - Kenji O., Japan
"Consistent Japanese quality. Even at high speeds, the edge stays sharp. CCMT060204 fits perfectly in our boring bars."
⭐⭐⭐⭐ "Great for Finishing Passes" - Sarah W., USA
"I use these for final passes on small diameter parts. The chip control is excellent even at 0.5mm depth of cut."
⭐⭐⭐⭐⭐ "Excellent Heat Resistance" - Felipe M., Spain
"Ran these dry on a few tests and they held up surprisingly well. CVD coating is definitely thick and durable."
⭐⭐⭐⭐⭐ "Original and Fast Shipping" - Chuan H., Malaysia
"Genuine Tungaloy inserts. Arrived in perfect condition. Performance is night and day compared to generic brands."
Technical Q&A
Q: Is T9115 suitable for Stainless Steel?
A: T9115 is optimized for Steel (P). For Stainless Steel (M), Tungaloy's T6120 or AH series grades are generally more effective against notch wear.
Q: What is the difference between 0.4mm and 0.8mm radius?
A: This 0.4mm (04) radius provides lower cutting forces and better precision for fine finishing, whereas a 0.8mm radius offers more edge strength.
Q: Can I use this for boring operations?
A: Yes! CCMT060204 is one of the most common inserts for small-diameter boring bars (SCLCR06) in CNC machining.
Machining Tip: CVD vs. Cermet
While Cermet (like NS9530) is great for mirror finishes at high speeds, CVD Coated Carbide (like T9115) is the superior choice for production stability and toughness in interrupted cuts or when machining tougher alloy steels. It provides the reliable indexable turning tool performance needed for heavy-duty precision machining.
